1. Irreversible white ink for leather cutting.
The ink is white color in room temperature, and becomes transparent when temperature reach setting point.
You can apply this material as a drawing pen in the cutting process of leather, clothes, and so on. The drawing line can be seen in white color during the cutting process, and will disappear in curing/setting process, so there is no need to clean or erase the line.
2. Irreversible photochormic material.
Irreversible photochromic material is a material that can change color from light green to Dark Green when exposed to Sunlight/UV light.
It’s one time reaction, and the color won’t come back again. This material can be used as an indicator.
3. Memory Type thermochromic material.
This material is a heat sensitive material.
We have six colors so far.
The color will start to disappear when temperature reaches 40℃, however, unlike the normal thermochromic pigment, the color will appear again when temperature turns back to 7℃.
This wide activated and de-activated temperature range makes the color having the character of memory.
4. Irreversible thermochromic ink.
This is a water based ink that will change from white to Black or Magenta when temperature heating to specific temperature.
We so far have 60℃,75℃,90℃,and115℃.
